Recently I used DigitalOcean's 1-click droplet with Gitlab 6.3 already installed. I did this without any guide so I ran into some problems.
From the very beginning, after the droplet was created I was able to see the Gitlab's login screen at my droplet's ip address Sadly,
I got stuck when I was not able to find the admin email and password to start using Gitlab. After searching, I found this guide where the username and password is mentioned:
Following this guide I was able to configure my user until I got blocked trying to add my ssh keys to my profile in GitLab. I would get the following error:
500 We're sorry, but something went wrong.
Looking into the logs I found that it was caused by GitLab running out of memory.
I had a droplet with only 512Mb of RAM. After upgrading my droplet to 1Gb of RAM I was able to add my ssh-keys without problem.
That's it for now!
